my understanding is that the original draft of the script had humans being used as a massively parallel distributed processing network. their own brains were the wetware that run the matrix simulation program. that's more sensible and a much more profound statement as to the philosophical connections between the matrix and the social construction of consciousness, which was a major theme of the film. but then some shit-for-brains hollywood producers read the script, decided it was too intellectual/nerdy and had it rewritten as "humans are batteries" which is gibberish to anyone with an education, but hollywood loves the lowest common denominator.
